A process which Eesti Energia began in 2001 achieved certification of the environmental management systems according to ISO 14001 for most subsidiaries by 2005, and all production units have been certified.
We intend to bring all subsidiaries within the verified Eco-Management and Audit System, which is similar to ISO 14001 but a bit stricter and demands that enterprises behave better than the environmental restrictions in force and that they publish an extensive public environmental report.
